Technical Field

[0001] This utility model relates to the field of housing technology, specifically to a wall-mounted ultrasonic flow meter housing that facilitates the disassembly of the flow meter. Background Technology

[0002] An ultrasonic flow meter is a type of flow meter developed based on the principle that the propagation speed of ultrasonic waves in a flowing medium is equal to the vector sum of the average flow velocity of the measured medium and the velocity of the sound wave in a stationary medium. It mainly consists of a transducer and a converter, and there are different types such as Doppler method, velocity difference method, beam deflection method, noise method and correlation method.

[0003] An ultrasonic flow meter is composed of various parts. The wall-mounted ultrasonic flow meter housing is one type of ultrasonic flow meter. For example, Chinese patent disclosure (announcement number): CN217424456U, discloses a wall-mounted ultrasonic flow meter comprising a housing and a fixing plate. The housing includes a back plate and a front housing. The fixing plate is fixed to an external wall and has a snap-fit ​​groove. A snap-fit ​​device is provided on the outer side of the back plate. The snap-fit ​​device includes a snap-fit ​​shell and a limiting mechanism. The snap-fit ​​shell is inserted into the snap-fit ​​groove, and the outer side of the snap-fit ​​shell mates with the inner side of the snap-fit ​​groove. The limiting mechanism includes a limiting block, a spring, and a pull ring. The limiting block extends from the outer side of the snap-fit ​​shell. Extend and abut against the inner side of the snap-fit ​​groove; pull the pull ring, and the spring will cause the limiting block to retract, snapping the back plate into the snap-fit ​​groove. After that, release the pull ring to reset the limiting block, so that the limiting block abuts against the inner side of the snap-fit ​​groove. This application has the effect of making it easy to disassemble and install the ultrasonic flow meter when it needs to be fixed on the wall for maintenance or replacement. The above patent has the effect of making it easy to disassemble and install the ultrasonic flow meter when it needs to be fixed on the wall for maintenance or replacement.

A rotating disk 33 is fixedly connected to the surface of the rotating rod 32. A transmission shaft 34 is fixedly connected to both sides of the front of the rotating disk 33. A transmission frame 35 is sleeved on the surface of the transmission shaft 34. A clamping plate 36 is fixedly connected to the outside of the transmission frame 35.

[0027] refer to Figure 1 The housing 1 includes a housing 101. The back side of the inner wall of the housing 101 is fixedly connected to the back side of the rotating rod 32. A wrapping ring 102 is fixedly connected to the front side of the housing 101. A fixing shell 103 is fixedly connected to the top of the wrapping ring 102. A sensor 104 is fixedly connected to the top of the fixing shell 103. A wall connecting plate 105 is fixedly connected to the back side of the housing 101.

[0028] As a technical optimization of this utility model, the flow meter 2 can be protected by setting the housing 1. The user installs the wrapping ring 102 on the front of the housing 101, then installs the fixing shell 103 on the top of the wrapping ring 102, and then installs the sensor 104 on the top of the fixing shell 103. The flow meter 2 is wrapped by the wrapping ring 102 and the housing 101.

[0029] refer to Figure 1 The flow meter 2 includes a flow meter 21. A transparent plate 22 is fixedly installed on the front of the flow meter 21. A bolt 23 is provided on the front of the flow meter 21. The back of the bolt 23 passes through the flow meter 21 and extends into the interior of the housing 101, where it is threadedly connected to the interior of the housing 101. The back of the screw sleeve 24 contacts the front of the flow meter 21. The front of the positioning shell 31 passes through the interior of the flow meter 21. The side of the clamping plate 36 away from the transmission frame 35 passes through the interior of the flow meter 21.

[0030] As a technical optimization of this utility model, by setting the flow meter 2, it can be fixed inside the housing 1. The user installs the transparent plate 22 on the front of the flow meter 21, then installs the flow meter 21 inside the housing 101, and then fixes it by passing the bolt 23 through the front of the flow meter 21.

[0031] refer to Figure 3 A fixed bearing 4 is fixedly connected to the surface of the rotating rod 32, and the surface of the outer ring of the fixed bearing 4 is fixedly connected to the front of the inner wall of the housing 101.

[0032] As a technical optimization of this utility model, by setting a fixed bearing 4, the rotating rod 32 can be fixed to prevent the rotating rod 32 from moving back and forth.

[0033] refer to Figure 3The inner wall of the positioning shell 31 has grooves 5 on both the front and back sides. A slider 6 is slidably connected inside the groove 5. The side of the slider 6 closest to the transmission frame 35 is fixedly connected to the transmission frame 35.

[0035] refer to Figure 2 A connecting block 7 is fixedly connected to the surface of the wrapping ring 102, and a connecting hole 8 is provided on the front side of the connecting block 7.

[0036] As a technical optimization of this utility model, by setting the connecting block 7 and the connecting hole 8, the front of the wrapping ring 102 can have a connecting effect, so that the front of the wrapping ring 102 can be connected to the protective parts, and the flow meter 2 inside the wrapping ring 102 can be protected by the protective parts.

[0037] The working principle and usage process of this utility model are as follows: In use, the user inserts the flow meter 2 into the housing 1, ensuring the front of the positioning shell 31 faces the flow meter 21. Then, the housing 101 is rotated, causing the rotating rod 32 to rotate. The rotating rod 32 then rotates the rotating disk 33, which in turn moves the transmission shaft 34 outwards. The transmission shaft 34 moves the transmission frame 35 outwards, and the transmission frame 35 moves the clamping plate 36 outwards, inserting it into the flow meter 21 to secure it. Finally, the bolts 23 are tightened. The flow meter 21 is inserted into the housing 101 from the front and fixed in place. To disassemble, the user first removes the bolt 23, then rotates the housing 101 in the opposite direction. The housing 101 drives the rotating rod 32 to rotate in the opposite direction, which in turn drives the rotating disk 33 to rotate in the opposite direction. The rotating disk 33 drives the transmission shaft 34 to rotate in the opposite direction, which in turn drives the transmission frame 35 to rotate in the opposite direction. The transmission frame 35 drives the clamping plate 36 to rotate in the opposite direction, thus separating the clamping plate 36 from the flow meter 21. Then, the flow meter 21 is pulled forward to separate it from the housing 101.

[0038] In summary, this wall-mounted ultrasonic flow meter housing, which facilitates disassembly, allows for the fixing and loosening of the flow meter 2 via a fixing mechanism 3. This separates the flow meter 2 from the interior of the housing 1, eliminating the need for numerous bolts during installation and preventing bolt stripping over time. The ultrasonic flow meter is also easy to separate and assemble from the casing, facilitating user disassembly and ensuring normal operation.
